Do soft snake plant leaves mean it needs water?
No. Soft leaves are not a watering cue. Check the deeper mix and drainage before deciding what action is appropriate.
Does a soft snake plant leaf confirm root rot?
No. Soft tissue is a warning observation. Inspect the root zone, drainage, and tissue pattern together rather than assuming one cause.
Can I save a soft snake plant leaf by propagating it?
Do not propagate visibly soft material as a workaround. First assess the plant's condition and use firm, healthy material only when propagation is appropriate.
